General information
Introduction
3 Introduction
3.1 General information
3.1.1 Content of this manual
This user manual illustrates:
• The installation of the FSE24B EtherCAT
®
communication option in the
MOVITRAC
®
B frequency inverter.
• The startup of MOVITRAC
®
B in the EtherCAT
®
fieldbus system.
• The configuration of the EtherCAT
®
masters via XML files.
• The operation of MOVITOOLS
®
MotionStudio via EtherCAT
®
.
3.1.2 Additional documentation
For information on how to connect MOVITRAC
®
B simply and effectively to the
EtherCAT
®
fieldbus system, you should request the following documentation on fieldbus
technology in addition to this user manual for the FSE24B EtherCAT
®
option:
• Manual "MOVITRAC
®
B Communication and Fieldbus Unit Profile"
• MOVITRAC
®
B system manual
Apart from describing the fieldbus parameters and the corresponding coding, the
"MOVITRAC
®
B Communication and Fieldbus Unit Profile" manual and the
MOVITRAC
®
B system manual provide examples to illustrate the different control con-
cepts and possible applications.
3.2 Characteristics
3.2.1 MOVITRAC
®
B and EtherCAT
®
The unit behavior of the inverter that forms the basis of EtherCAT
®
operation is referred
to as the unit profile. It is independent of any particular fieldbus and is therefore a uni-
form feature. This allows the user to develop fieldbus-independent drive applications.
This makes it much easier to change to other bus systems, such as CANopen (option
FSC).
3.2.2 Access to all information
MOVITRAC
®
B offers digital access to all drive parameters and functions via the
EtherCAT
®
communication interface. The frequency inverter is controlled via fast, cyclic
process data. You can use this process data channel to enter setpoints (e.g. setpoint
speed, ramp generator time for acceleration/deceleration, etc.) and to trigger various
drive functions such as enable, controller inhibit, normal stop, rapid stop, etc. At the
same time you can use this channel to read back actual values from the frequency in-
verter, such as the actual speed, current, unit status, error number and reference sig-
nals.
3.2.3 Cyclic data exchange via EtherCAT
®
Process data is usually exchanged cyclically between the EtherCAT
®
master and the
MOVITRAC
®
B frequency inverters. The cycle time is specified during the configuration
of the EtherCAT
®
master.
